Build the experience. Let the backend work with you.
For design studios, digital agencies and app builders who want to give clients a product of their own without hand-coding another backend for every project. APPSS helps model, connect and operate the data, rules, access and actions behind your design.
A project-scoped managed service. Not a self-service account or unlimited API you can activate today.
Your design in front. Agreed business logic behind it.
Start with one real customer task. Your team designs the experience; together we define the information, permissions and actions the application needs.
Your team
Experience
A web, PWA or native interface that fits its users.
APPSS
Managed application layer
Data, rules, actions and controlled access.
Existing environment
Sources
ERP, CRM and other systems where they remain authoritative.
The backend capabilities your product actually needs.
This is not a blanket promise that every system or connector is already available. For each product, we select the building blocks, define their behaviour and agree what APPSS operates.
Data and records
Which facts does the application use, where is the source and what gets recorded?
Rules and decisions
Make conditions, exceptions and human approval explicit before they drive behaviour.
Identity and access
Decide who can see, propose, approve or perform each action.
Messages and agent tasks
Let business messages trigger next steps, with boundaries and checks for agents.
APIs and integrations
Agree a versioned contract for your frontend and the systems it connects to.
Operations and change
Define monitoring, backups, support, controlled changes and recovery as part of the service.
Describe what should happen. Review before it does.
An authorised builder or agent can prepare a model or configuration change through agreed interfaces. APPSS does not treat a proposal as automatic approval. Checks, tests and release belong in the workflow.
Describe
Express data, rules or a new task in language people can review.
Review
Check the proposed change against permissions, exceptions and existing agreements.
Apply
Release approved changes in a controlled way and observe the outcome.
API access and agent interfaces are specified and tested per project. This page does not provide a public API or unrestricted agent access.
Sovereignty is an agreement you can verify.
European deployment is a delivery requirement for this offer, not a conclusion about where this marketing site is hosted. Before production, we define the supplier, region and location of processing, storage and operations.
Choose the infrastructure behind the managed service.
We start with the same infrastructure options as DataStreams. The European region, services and responsibilities are agreed for each APPSS application.
Hetzner: Germany or Finland
A possible European cloud or dedicated option. We agree the location and operating boundary before delivery.
STACKIT: Germany or Austria
A possible European cloud option where control over infrastructure and processing is a priority.
Your infrastructure: Dedicated or on-premise
A client-controlled or selected environment may fit. We first assess the technical and operational conditions.
The marks identify infrastructure options, not provider endorsement or proof that APPSS already runs in each environment. The final choice is agreed per project.
Data and processing
Where do primary records live and where are they processed?
Logs and backups
Where does derived data go and how long is it retained?
Access and suppliers
Who has support or admin access, which subprocessors are involved and under what terms?
Portability
How can the client take their data, model and agreed interfaces if the relationship changes?
Region, suppliers, contracts and technical controls must be demonstrable for each customer environment before a specific sovereignty guarantee is made.
Less backend code. No less responsibility.
The goal is to stop rewriting common backend functions as bespoke code for every product. Design, frontend development, unusual integrations, security, testing and support remain real work. We agree what the managed service covers for each application.
A design team with a real product idea?
Describe one user action and the data and rules behind it. That gives us a starting point for the managed capabilities, APIs and European deployment requirements this project needs.
The current intake only creates a local conversation brief. It does not create an account, backend or submitted request.
